Abstract

We observed laser emission in whispering gallery modes using a microring composed of a light-emitting semiconducting polymer poly[2,5-bis-(2'-ethylhexyloxy)-p- phenylenevinylene] (BEH-PPV) coated on an etched fiber under transient and quasi steady-state pumping conditions. The threshold for laser oscillation was 1 mJ/cm² (0.1 MW/cm²) and 30 (mu) J/cm² (300 MW/cm²) for nanosecond and femtosecond excitation, respectively. The laser output showed superlinear dependence on the excitation energy above the threshold. The demonstration of lasing under quasi steady-state pumping shows the possibility to develop electrically pumped polymer lasers. Preliminary results on the line narrowing in tripheny dilamine (TPD) films under nanosecond optical pumping are also presented. 23
